ICE MAKER NAMEPLATE LOCATED ON BACK PANEL SERIAL PLATE LOCATED BEHIND FRONT PANEL January 2000 Page 3 NME954R & WRF736SDAB FOR THE INSTALLER Installation Limitations: The machine and bin are designed to be installed indoors, in a controlled environment: Min Air Temperature Water Temperature Water Pressure (PSI) Voltage 500F 1000F 1000F 80 253 Max Location Install the machine in a location where it has enough space around it to be accessible for service, usually a minimum of 6 inches. Try to avoid hot, dirty and crowded locations. Be sure that the location for the machine is within the limitations. (Not including the remote condenser) 400 20 198 Storage Bin (Compared to the nameplate) Operating the machine outside of the limitations is misuse and can void the warranty. [. . . ] After the evaporator, the refrigerant, now a low pressure vapor, goes through the suction line back to compressor, where the cycle is repeated. ·Suction pressure: 35 PSIG Compressor Amps ·3 Phase - 2. 8 ·Discharge pressure: 255 PSIG ·Minimum Discharge pressure (low temp): 180 PSIG ·Single Phase - 4. 3 Remote Condenser Discharge Line Liquid Line Detail Of Head Pressure Control Valve Liquid Line Valve Thermostatic Expansion Valve Head Pressure Control Valve Evaporator King Valve Suction Line Receiver Compressor January 2000 Page 19 NME954R & WRF736SDAB OPERATION: Refrigeration Low Condensing Temperature The refrigeration system under low condenser air temperatures is much the same as it is under higher temperatures, with the exception that the resulting low head pressures cause the head pressure control to close off the liquid line between the condenser and the receiver. This forces more refrigerant into the condenser (with a small amount of discharge gas going into the receiver to maintain SCHEMATIC OF DISCHARGE PRESSURE CONTROL VALVE, Normal Temperature Valve Disk pressure the valve opens up the liquid line from the condenser to the receiver. SCHEMATIC OF DISCHARGE PRESSURE CONTROL VALVE, Low Temperature From Compressor From Compressor To Receiver To Receiver From Condenser From Condenser pressure until the head pressure is built back up to the rated gauge pressure of 180 psig). At that PUMP DOWN During the pump down cycle (usually initiated by the circuit board de-energizing the liquid line valve) the discharge gases flow through their normal path to the remote condenser, through the head pressure control, and into the receiver. At this point the refrigerant flow is stopped by the closed liquid line valve. This action forces the refrigerant into the receiver and keeps it out of the compressor. The pump down continues until the low pressure control turns the compressor off. January 2000 Page 20 MAINTENANCE AND CLEANING NME954R & WRF736SDAB It is the USER'S RESPONSIBILITY to keep the ice machine and ice storage bin in a sanitary condition. Without human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their water systems with a specifically designed chemical. That chemical dissolves mineral build up that forms during the ice making process. Sanitize the ice storage bin as frequently as local health cods require, and every time the ice machine is cleaned and sanitized. DO NOT USE any ice produced from the cleaning solution. Add warm water to the ice storage bin and thoroughly wash and rinse all surfaces within the bin. Sanitize the bin interior by washing the interior of the bin with the balance of the sanitizer solution. Return all panels to their original positions. 8. Slowly pour the cleaning solution into the water reservoir until it is full. Wait 15 minutes, then switch the master switch to ON. As the ice maker begins to use water from the reservoir, continue to add more cleaning solution to maintain a full reservoir. After all of the cleaning solution has been added to the reservoir, and the reservoir is nearly empty, switch the master switch to OFF. January 2000 Page 21 NME954R & WRF736SDAB Sensor Maintenance 1. The bin control uses devices that sense light, therefore they must be kept clean enough so that they can "see". At least twice a year, remove the bin control sensors from the base of the ice chute, and wipe the inside clean, as illustrated. Ice Chute 2. The ice machine senses water level by a probe located in the water reservoir. [. . . ] If the ohmmeter does not show any change, or shows and open circuit, replace the switch or motor. To Remove and Repair the Gear motor Assembly: (Assuming that the procedures through removal of the water seal have been performed. ) 1. Remove the electrical wires from the gear drive motor. Unscrew the 4 cap screws holding the gear motor to the unit. [. . . ]
